Tower 55, Modern high-rise building in downtown San Jose, California.
Tower 55 is a modern 15-story high-rise in downtown San Jose with a distinctive gold-tinted glass exterior. The building stands at the corner of South Market and Post Streets and houses office tenants alongside telecommunications equipment and infrastructure.
The building was completed in 1985 and later became a major hub for internet connectivity. The telecommunications facility on the 13th floor served as a key data exchange center for the northern California region.
The structure represents the evolution of Silicon Valley architecture, combining office spaces with advanced telecommunications infrastructure in downtown San Jose.
The building is easily accessible from South Market Street or Post Street and serves multiple business tenants. Since it functions as a commercial office building, public access to the interior may be restricted.
The building housed MAE-West, one of the earliest major internet exchange points that enabled data flow between different internet service providers. This role made it a critical node in the early history of commercial internet infrastructure in California.
